Wilson Sonsini Advises Alianza on Acquisition of Metaswitch
Client Highlights
March 5, 2025

On March 4, 2025, Alianza, Inc., the world’s first cloud-orchestrated, AI-powered communications platform dedicated to service providers, announced the completion of its acquisition of Metaswitch from Microsoft, executing on the Definitive Agreement announced in December 2024. Financing of the transaction was provided by existing Alianza investors and a syndicate of commercial banks led by Wells Fargo. Wilson Sonsini Goodrich & Rosati advised Alianza on the transaction.

The combined offerings of Metaswitch and Alianza will enable service providers to close a massive gap in their ability to grow services revenue and improve operational efficiency by modernizing core networks, unlocking new innovative offerings, and ultimately transforming network operations. With the close of this transaction, Alianza will serve a combined customer base of more than 1,000 communication service providers, including 19 of the top 20 global operators. Alianza will continue to support Metaswitch’s existing product offerings while integrating its cloud-native technology into a unified product portfolio.
